Application filed July 22, 1912. Serial No. 710,967.

To all (If/l), it may concern:

lie itknown that l, Jonx F. Donurnnn.v citizen of the United States, residing at. t lhicago. in the county of Cook and State Illinois have invented certain new and useful improvements in Malt-'lurning Machines: and I do hereby declare the follo\\-'- ing to be a full, clear, and exact description of the invention, such as will enable others to skilled in the art. to which it appertains to n-ialt'e and use the same.

This invention relates to improvements in malt turning machines particularly adapted for use in malt houses of the type known as the Saladin, and has for its object. to provide a simple and etlicient machine of this character adapted to stir and turn over malt contained in the malting compart ments.v

The invention consists in the features of construction and combinations of partshere inatter fully described and particularly claimed.

In the accompanying drawings illustrating the invention: Figure lis a plan View of a malt turning inachine constructed v in-acct-n-dancc with Xl'lYlltYCllbiOIl. Fig--2- is an end elevation of the same. Fig.3 is a. fragmentary front elevation of the same; Fig. 't is a detail vertical teens verse section of the same on the line 4- of Fig. -'-3-. Fig, 5-- is adetail vertical section on the line 55 of Fig. (4- Fig. -t' is a vertical transverse sectid'n the machine on the line (t-G of Fig. l. E ie m 7 a top plan view of a helix employo.

Fig. S-- is a side elevation of said helix.

The invention relates more particularly to certain details of construction of the Ina-- chiue and to imprm ements in the helix actuated thereby for turning the malt during travel of the machine in the compartment as will particularly appear from the following spmzitication.

()n the side walls of the i'naltingcompartmeats. of pneumatic malt houses of the Haladin type. the umstruction'of which are \velll no\vn; there are mounted two rails consisting preferably of channel bars upon which the carriage of the malt turning ma chine is supported in travel. The said channel bars carry l'itt'li bars over their entire length which are adapted to be engaged lrv llttt' pinion: carried bv the nrtcleiue for In the drawings the channel bars referred to are indicated at 1 and the rack bars at 2, the latter being engaged by the spur pinions or gears 3 of the malt turning machine. The latter comprises a carriage consisting of end plates 4. which are connected together by means of channel bars 5 disposed parallel with each other. and suitably secured to saidend plates. Each of the end plates car ries v two wheels (3 rotatably mounted on studs carriedther'eby and which travel upon the upper flanged edges of the channel bars 1. the drive shaft. 7 of the machine, carrying the sheave 8, is jonrnal ed in a bearing 9 on the arm of a standard to atone end and at its other end in a bearing 11 in the standard 12 supported at its ends upon the upper edges of the channel beams 5 constituting part of the frame-or carriage of the machine.

Similarly supported in bearings carried by the said standards lOand 12 is the inclined counters-hath 13' carrying a sheave l t, one portion of the periphery of which is disposed in horizontal alinemen't' withthe periphery of the sheave 8 and over which the ropeor cable 15 is trained, the, said sheave 14 being" idle and adapted to permit the said drive rope or cable 17 to pass the sheave 8 laterally thereof in a well k-novvu manner. The said shaft 7 carries a spur pinion 16 which meshes with the spur gear 17 on a countershaft; 1S journaled in bearings 19 otthe standard 10 and a bearing; 20 in a standard 21 supported on one of said channel beams Rigid with said countershaft i8 is a spur pinion 21 which meshes with the. spur gear 22 carried by the shaft 23 journaled in a bearing" carried by saidstantb ard l0 and in bearings carried by a plu rality oi boxes or gear cases 21 disposed at intervals between the end plates of the machine. Rotatably rigid with saidshaft- 2 and disposed in each of said gear cases 24 is a bevel pinion 25 which meshes with the bevel gear 26 rigidly disposed on a vertical shaft. 27 carrying one of said helices which will be hereinafter full), described. The said shaft 27 is journaled in a bearin 2S carriedby' and integral with the lower wall of one ot said gear boxes l-t and in a bearing. 29 carried by and disposed between the channel bars 5, said lastaialued bearing receiving at its upper end the bearing 28 for purpcses which will be hereinafter fully described. The said bevel pinions 2? are so disposed relative to the several bevel gears as to drive alternate shafts 37 in respectively opposite directions, the helices carried by said shafts being disposed respectively right'and left in the manner of right and left screw' threads. The shaft 23 is jour limited extent to relieve the same of ex-.,

cessive strains. That is to say the shaft 23 is free to yield slightly laterally about a r. .iy be of any fulcrum coinciding wit-h the axes of the shafts 27 when the helices carried by the latter encounter more than ordinary resistance, as in starting.

It will be noted from the foregoing that the train of gears heretofore described serves to rotate only the shafts 27 and the helices carried thereby, but has no effect upon the travel of the carriage of the ma-. chine upon the channel bars 1. The gearing for causing travel of the latter will be now particularly described.

Disposed parallel with the shaft 23 is a countershaft 3O journaled in a bearing 31 carried by a gear box 32 suitably supported upon the carriage. Said shaft 30 carries a sprocket 32 over which and a sprocket- 33' on the shaft 23 .a sprocket chain 34 is trained. The said. shaft 30 carriesa bevelgear 35 which meshes with two bevel gears 36 on a vertical shaft 37 journaled in'bearings 38 in said gear box 32. The said bevel gears 36 are loosely mounted on said shaft 38, the latter carrying between said bevel gears a clutch 39 which is slidable thereon but rotatably ri id therewith. Said clutch desired pattern adapted for the purpose but in the instance illustrated is oft-he toothed type and is adapted to engage in the-toothed clutch members 40 car,-

A lever ricd by said respective gears :36. q 41 carried by a horizontal shaft 42 engages said clutch member 39 and serves to throw the same into engaging relation to either of said clutch members 40 carried by the gears 36. Thesaid shaft 42 is journaled' at one end in a bearing carried by said ,gear box 32 and in its other end in. abearingjsupported in an arm 43 of one of said end plates 4.

Contiguous to the last-namedbearing said.

shaft carries'a lever 44 by means of which it is turned to throw said clutch 31 into and out of engagement with said respective .lcl'utch members 40 of said gears 36'. A

weight 45 is carried by said shaft 42 and is caliable of limited rotation relatively thereto] said weight being adapted to be thrown overiito either side of the vertical plane of the axis of said shaft 42 in order to maintain the said shaft in'a position to maintain the. ciiii tch 39 engaged with one of said respective gears 36. Suitable stops 30 are carried by one of said channel bars 1 contiguous toseither end thereof and in the path of said lever 44 so that as the carriage of the machine approaches either limit of its travel the said shaft 42 will be automatically turned to throw the clutch 39 out of engagement with the clutch member 40 t-heretofore engaged thereby thus bringing said carriage to a standstill. 37 carries a spur pinion 46 which meshes The said shaft with a spur gear 47 on a vertical shaft 48, i

the latter being journaled in a'sleeve bearing 49 secured to said gear box 32 and supported by the latter. The said spur gear 47 is loose on said shaft 48 and the, hub thereof v constitutes a spur pinion 50 which meshes with a spur gear 51 rotatably mounted upon the upper;bearing.of the gear. box-'32 in which said shaft,37 is journaled'and is thus rotatable on'an axis concentric with that of said shaft 37. The hub of said spur gear 51 also constitutes a spur pinion 52 which meshes with the spur gear 53 rigid with said shaft 48 and which drives the latter. train of gears above described s'ervesto impart very slow rotation to said-shaft 48 as will be obvious, and it maybe readily increased or diminished to varywthe speed of rotation of the helices relative to the speed of travel of the carriage, which is very advantageous and important. The shaft'48 carries a bevel pinion 54 at its lower end.

varies also, becoming greater as the width- The of-the compartment increases. If the helix makes one revolution for each inch of travel of the carriage or makes two revolutions in. the same intervalsmalresa vast difference in resistance, becoming less as the speed of ro..

tation of the helices increases because the latter loosen thebody of malt more thoroughly. It is, therefore, importantthat the gearing employed should readily adapt itself to variation at sm'allrcost and trouble so that the relative speeds of the parts men-' tioncd may be easily adapted tothe particular conditions pertaining in-each case. At both its ends said shaft 56 carries a spur gear 57 which meshes with the spur gear 3 meshing with the rack 2 carried by the.v

channel bars 1 for causing' the carriageto travel upon the last-named channel bars. The gearing last described is also inclosed in suitable gear boxes for the purpose of protecting the same against the moisture present in all malt houses and further to prevent is greatly enhanced.

in turning or stirring and agitating liarley or other grain in process of germination it is not only wet and thus inclined to lump From this cause but the sprouts sl'iootinfi therefrom entangle themselves with each other and with the contiguous kernels so that the tendency and power to form hig lumps This tendency to form lumps is a source of considerable annoyance inasmuch as frequently a large lump or ball of n' rininated grain heroines caught in the helices and is rotated with the latter thus greatly increasing the resistance torotatiou thereof and din'iinishing the ellieienev of the helices in turnin i over and stirring the body of the germinated grain. The. helices which I have invented and will now proceed to de scribe are equipped and designed to break up such lumps or halls ofgern'iinated grain to prevent the same from being rotated therewith.

Seeured to-eaeh of the vertical shafts-QT diere are seem-ed at diflerent elevations rollars 57 each of which is equipped with an arm 5S, the'latter heiug curved and pr sentin a convex edge in the direction of rotation of said shaft At the. lower end of each of said shafts 27 there mounted a coliar 59 carrying an arm or toot-piece (it) which is also curved and presents a convex edge in the direction of rotation pfithe. helix. lhe

carries a' projeeouter end of said arm v tion (31 which is (1l51)()1.(l coneentric with the shaft 27 and is .n'ov.i 'le( l-in upper face. with a recess which receives one end-of the helix 62, the latter heing suitably secured by means of rivets. Between each of the. arms :38 of said collars '57 and the lower face of the helix there is mounted a separator sleeve (33 through which the bolt (34 or other fastening device Suturing said helix 1:. the arms 58 is adapted to pass. -The several arms 58, any desired number of which may he en'iployed, are thus maintained separated from the helix hya space sui'l' iently deep to prevent the formation at the juncture of the. tube of a corner in which a hall or lump of the moist germinating grain is adapted to be caught'and held so as to ro tate with said helix. The latter consists of a. strip of relatively heavy steel bent to helical form, as shown. The curvature of the arms. 78 and of the-front edge of the foot PlflCk .30 tends to eanse the grain contacting with said convex edges to move outwardl toward the'helix so that the action of the device throughout to ca use the grain to he raised and turned over and moved out wardly from the shaft toward the helices so that all portions of the grain in the com partnient will be fully agitated and loosened up to permit aii to pass theretln'ough.
